| Nowadays,the audit opinion issued by accounting firms is an important basis for the expected users of financial reports and stakeholders to make economic decisions.the process of its development and whether the audit quality adapts to the economic development has received attention from all walks of life.High-quality audit plays a vital role in the CPA industry,and it is also an important foundation for accounting firms to achieve rapid development and establish a good reputation in the industry.The quality of audit work of the firm is affected by many external and internal factors,and the definition of responsibility and legal risk of certified public accountants are different in different organizational forms,which makes the organizational form become an important factor affecting the quality of audit.In 2010,the Ministry of Finance issued the interim provisions on promoting large and medium-sized accounting firms to adopt special general partnership organizational forms to encourage domestic large and medium-sized accounting firms to gradually begin to change their organizational form.Nine accounting firms,including Lixin,Zhongrui Yuehua,Tianjian,Xin Yonghe and Daxin,actively followed the policy to achieve transformation in 2011.This paper focuses on whether the transformation of accounting firms has played a positive role in audit quality,what are the inherent defects and problems of the special general partnership and what corresponding measures should be taken.At present,most of the studies related to the transformation of firms focus on the theoretical inference that brings positive effects after the transformation,mostly by collecting large sample data to carry out empirical research,and using the method of alternative indicators to quantify audit quality.this empirical research method for a large amount of data is relatively rough and single,and it is lack of using a single domestic firm that has been converted as a case to carry out targeted analysis.At the same time,there is a lack of horizontal comparative analysis on the changes of audit quality of the two transformed firms.This paper creatively selects the first batch of accounting firms whose comprehensive strength is in the middle level as the main case object,and analyzes the changes of audit quality after the completion of the transformation in 2011.and in the process of case analysis,the bounden accounting firm,which also realized the transformation in 2011,is introduced as the object of horizontal comparison,so as to make the analysis of the case more comprehensive.The conclusion of the study can better represent the general level of the change of audit quality brought about by thetransformation.The transformation of accounting firms is also strongly encouraged and supported by the government,and for this reason,relevant policy documents have been issued many times,which is of great significance to the optimization of the entire industry,the expansion of scale,the standardization of the market,and so on.Domestic large and medium-sized accounting firms also actively respond to policies and strive to develop their own strength at the same time.Therefore,the method of case study can test the effectiveness of conversion policy and behavior to a certain extent.The purpose of this paper is to better enrich the relevant literature on the impact of the behavior of domestic firms on audit opinions,and can also provide reference for the information needed by the market,investors and regulators,and put forward suggestions for regulators to supervise better.we will promote the improvement and development of the market in a more healthy and orderly manner. |
